Remove everything, degrease. Clean the repair pads too.

En-glue with a slow glue. I am not qualified enough into gluing plastic to tell exactly what type is the best. I personally use slow bi-component epoxy glue.
Put some glue under the pads too.

Hold the pads and clean the un-useful glue as much as you can. You can also scratch it later but glue should not stay, as it will disturb the plastic flex circuit support positioning.

Hold it with... well maybe you have something better. Eventually screws from under the case would provide the best pressure. But don't en-glue the screws!

Last step:
Very delicately remove the guide by lifting it up, with both hands, without to move the pads.
Clean the guide from glue.
Clean the remaining glue under the guide.

Be patient, let harden long enough, rebuild.
I'd be curious to read your comments and how some of you did, in a similar case.

EDIT: Had forgotten to describe the last step!
